The dimension of directional diffusers in the SI device is 595x595mm. If you set an Imperial device directional diffuser (603x603mm) on the SI unit ceiling, it won't healthy. Exactly the same relates to other square-shaped ceiling diffusers.

If we now concentrate on the optimised design on the ideal, we begin to see the fittings employed stick to a A great deal smoother profile without unexpected obstructions, recirculation or backflow which considerably enhances the air stream price in the system.
